Review your financial model before you share it

Get started with Tessly

01

Upload the Excel model you already have

Start with an .xlsx file. Tessly identifies worksheets, periods, currencies, scale, and core financial line items.

02

Review what Tessly imported

Confirm that revenue, costs, headcount, cash, and other line items are mapped correctly before you continue.

03

Make key assumptions explicit

Turn pricing, customer growth, gross margin, hiring, and spending cadence into assumptions you can explain and compare.

04

Complete a pre-share review

Use the 12-question checklist to review formulas, sources, runway, and use of funds before you choose a version to share.

The goal is not to make finance sound more complex. It is to turn each question into something you can check.

Every guide explains when it applies, how to review the model, common red flags, and what Tessly can help with today.
